Coarse Bubble Disc Diffuser

Disc Diffuser is simple and sturdy. An upward facing convex dish is covered by a plastic membrane which encompasses the rim of the dish and perforated precision “I” slits. The dish is made of ABS, and plastic membrane is made from EPDM. This material is resistant to aggressive chemical attack, weathering and ageing. Thus, our diffuser is resistant to all common wastewater components. The outstanding “Inner Check Valve” design can make sure of non-backflow operation; the pipeline under the diffusers then won’t contain waste water any more
